How to Identify

A tree. It grows 4-8 m tall. The crown is sparse. The trunk is twisted. It is 20-30 cm across. The leaves are compound and twice divided. Leaves are alternate and 20-30 cm long. There are 18-24 leaflets. They are 5-6 cm long by 1.7-2.2 cm wide. The flowers are at the ends of branches. Flower stalks are 25-45 cm long. They are very showy and yellow. The flower stalks are 3-5 cm long. The stamen have different forms with long ones forming an S shape. The fruit is a woody pod. It is 40-70 cm long by 2-3 cm wide. The seeds are in a juicy, bittersweet pulp.

How to Grow

Plants are grown from seed. The seeds are harvested and scratched to break the hard seed coat, then planted fresh. They germinate in 2-4 weeks.

Propagation: Best sown as soon as the seed is ripe. The seed has a hard seedcoat and may benefit from scarification: pour a small amount of nearly boiling water over the seeds (taking care not to cook them), then soak in warm water for 12–24 hours. If seeds have not swollen, carefully nick the seedcoat without damaging the embryo and soak for a further 12 hours before sowing. Sow in a sunny nursery seedbed; germination should occur within 2–4 weeks. Young seedlings grow quickly.

Medicinal Uses

None known.

Other Uses

The wood is thick-textured, moderately heavy, soft, of low durability and easy to work. It is used locally for internal work in rustic house construction, tool handles, cheap toys and boxes. The species is a natural pioneer in its native range and could be used in local reforestation projects.
